I am planning an across-country road trip. I live in Washington State and have a Resident CWP. How do I bring a firearm (pistol) on the trip? What must I do, as an example, to transport the gun through Illinois, Alabama, Georgia, etc?
You’ll need to check on each state that you will be traveling through to find out their rules and regulations for traveling through their state with a firearm in the vehicle. Having a concealed carry license may or may not have an affect on the law within certain states.
I would suggest picking up a copy of The Traveler’s Guide to the Firearm Laws of the Fifty States and keep that on you. It is a great reference tool when traveling.
